I just wondered about something similar a while ago.
I wonder if Zer0’s B0re would work with Wotan?
I could see Maya beating it for sure, with all the elemental buffs going for her, and the CC she has. Also, the bee shield + Sandhawk, pretty much every character could beat the raid imo. I could see Maya using bee + pimpernel destroying wotan in seconds though. Krieg would probably have a rough time inthere, not really with the mobbing part, but Wotan. Although with the chain explosive skill he has (forgot the name), it might be doable. Sal is a no brainer for sure.
I can’t see anyone from BL1 doing it tbh, but then again I don’t really remember much of the skill trees anymore. Lilith’s phasewalk could come in handy at wotan though, and running a smg build, it might be doable. Double anarchies ftw!
From TPS, I only played Jack and willhelm, but I don’t have enough knowledge of the game to say wich one would able to clear it.
Edit: added a few VH’s
